GUSTAF SWENSON, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO UNDERWGOD TYYE-WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Oct. 25, 1910.

To all whom it may concern.

Be it known that I, GUSTAF Swanson, a citizen of the United States,residingin Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in. Typeriting Machines, of which the following is a specification. i.

This invention relates to devices usually provided at the side of a tywwritil lg machine for engaging the side edges of the sheets as they areplaced into position for writing.

Heretofore the side gage has been in the form of a. ledge turned up fromthe plate, the latter provided with a claw or book to fit tightly uponthe rolled upper edge of the paper s'helf, such as in the well known Un-It has been found thatthese hooks or 'claws must be so tight, in orderto hold the gage roperly upon the letter-feeding carriage, t at it isdiflicnlt to adjust thenralong the paper shelf, owing to their strongbinding action,

and moreover the shelf becomes scratched and marred.

The object of my invention is to provide for convenient and easyattachment and detachment of the gage from the paper shelf and easyadjustment therealong, without liability of marring the shelf, while thegage is held securely n position.

In the drawings forming a part of this application, Figure 1 is asectional side elevation of the platen frame of an Under-woodtypewriting machine, with my improvements applied thereto, and-Fi 2 1s aperspective view of the front of t e same, partly in section.

The usual latenl, is revolubly mounted in a lat'en rame 2, whichincludes an in cline paper shelf 3 in rear of the laten and forwardlyfrom which are arms 10, preferably of elbow form and carryin at theirforward ends a plate 11., bearing acewise upon the back of the papershelf 3 and cooperating with the plate 6 to form a clip.

- One or more springs 12 are carried by the shaft 9 and have one endpressing upon the claw 7, while the other presses on some portion of thearm or arms 10, to provide moderate pressure of the plate It on one Sideof the shelf and the plate (3 on the other side thereof, to hold thegage from jarring out of position during the intermittent movement ofthe carriage. This clamping action also keeps the plate 6 close againstthe shelf, to prevent the sheets of paper from getting between them; theclaw 7 having a pivotal action on the tubular rim 4, to permit thespring to do this.

By extending out the contact of the clamping member, as by the bar orplate 11, the

clamping member will tend to keep the plate 6 against the shelfthroughout its width, and the plate 5 at right angles to' the surface ofthe platen.

It is obvious that the gage may be shifted readily along the shelf toany position without scratching the surface-of the shelf, and that thegage firmly retains its position.

Having thus described my invention,

claim:

1. A device of the character described,

curved edge of said she f, and a spring pressed clip on said claw andextending forwardly to press against the'b'ack of the paper shelf, tobind said member thereto.

2. A device of the character described, comprising a member adapted tobe secured to the paper shelf of a typewriter to serve as a paper gage,said member having a claw curved to conform to the rolled edge of thesaid shelf, ears on said claw, a-pintle mounted thereon, a plurality ofdownwardly and forwardly extending arms carried b said pintle, a crossplate connecting sai arms and adapted to en age against the rear of thetypewriter shel to hold the gage against the front thereof, and springsto press said plate against the shelf.

3. A gage for the side edge of the sheet, to be attached to a papershelf and having 5 a claw 0r hook to catch over the top of the l\Vitnesses:

paper shelf and support said gage ivotally MAYNE R. DENMAN, thereon, anda spring clip pivotal to said C. E. Yos'r.

claw and extending forwardly to press against the back of the papershelf, to bind said gage thereto.
